A lesbian cop who celebrated a high-profile marriage in Central Park is about to file a $5 million suit against the city, charging harassment by her fellow officers and supervisors, her lawyer said yesterday.

Elizabeth Bryant was married to another woman cop in an elaborate ceremony on June 23, 1997. Almost immediately, fellow cops in the 42nd Precinct began tormenting her, said her lawyer, Joseph Tacopina.

Tacopina said he will file the lawsuit in Manhattan federal court Monday.

He said cops taunted Bryant with derogatory names, and posted obscene pictures with her face pasted onto them.

Bryant claims that when she filed complaints with supervisors, the abuse only increased.
